This is the PACKAGED DEAL (all 3 levels: Children's House, Lower Elementary, and Upper Elementary), the Full Montessori Scope and Sequence for nine years: ages 2.5 to 12 years. I included the corresponding state standards. If you follow this lesson schedule, you will hit all of the state standards. This is great to give administrators and parents. Much of it is organized by month, so you can organize your curriculum tubs to rotate the materials on your shelves.
